engine power is reduced, service stabilitrak and service traction control
Hello Sarah,
Need some help from GMC. I am the one owner of a 2013 GMC Sierra 1500 Texas edition and have changed the oil religiously every 5000 miles. This morning on the way to work my cam and lifters and apparently my stabilitrak traction control and abs all went dead at the same time. Parkway Chevrolet in Houston Texas is telling me it's going to cost $5,800 to get this fixed. Looking on the internet and through these forums I can see that this is a problem that has been plaguing the GMC and Chevrolet pickups. This is crazy and it is not affordable for me to fix.. please GMC will you reach out to me and possibly parkway Chevrolet to remedy the situation? I desperately need your help please please please help.

Had the same issue on my 2008 LT with a "#6 misfire" code. The final clue was an empty coolant reservoir. Pulled the #6 plug to find it was badly fouled. Acting on a hunch of a slight leak in the cylinder head gasket, used Blue Devil Cylinder Head Sealant. Good rep, but not cheap - $54 for a quart on sale. Followed the directions exactly. Put in a new plug. Now runs like a top. I was hesitant to use a sealant product vice pulling apart the motor to replace the gasket, ($1200 if you pay a pro,) but now a number of months and no problems.
Hi all,
two weeks ago my avalanche 2007 z71 started showing these three warnings
engine power is reduced , service stabilitrak and service traction control
I took it to the dealer and he said the problem was " throttle body" p2145
so I changed it , after a week the problem came back
this time the dealer said the " throttle body" was not learned, so he made it learned or whatever
this week the same problem came again !
I want to mention that the engine turned off "de-energized" while I'm driving three times !
Any ideas ?

Hello, sorry to bother you but did you ever find out what was wrong? Im having the exact issues with a 2008 tahoe ltz
I'm having a similar issue with my 07 avalanche. I've replaced the throttle body and cleaned the filter with throttle body cleaner. My codes for service StabiliTrak, service traction control still came back after a few days. Now they come and go but I don't feel any difference in the driving. I do however feel a vibration at around 40-55mph, this only occurs while on the gas. If I let off the gas the noise stops but then it's this slight skipping/grinding type sound coming from the rear. I'm under the assumption I need to change my rear wheel bearings or u joint. I've replaced both front CV axles, rechecked and retightened all of the bolts, lug nuts and etc but the vibration and noise are still there. also, my park assist is on but I figure that's just a sensor. any help for any of the problems above?

I need GM Customer Service to message please
Just wait I am in talks with a class-action attorney because Cadillac had also the same problem Cadilac , but unlike Chevy owners Cadillac owners complained to GM like I did and eventually Cadillac extended the throttlebody warranty and got everything covered for those who had problems so complain to GM call them and complain so that it is on the record .
I NEED EVERYONE TO COMPLAIN TO GM!! Don’t just fix it.
Email me your info so I can forward it to my attorney. They need more people to come forward with this problem so that they could actually have a case on their hands.

did you ever get this resolved? If so what did you do having same issues with my Chevy 2011 impala it’s frustrating

My name is Brenton Wilkie and my email is Brentonlwilkie@gmail.com. I have a 2015 impala and I've been having trouble with my Stabiltrak ever since I got the car. It jerks at times cause of the engine reduce power and the constant ding ding every 3 seconds. Ridd in the car for 4 straight hours and listen to it ding ding every 3 sec. I really need help please.
i'm having the same issue with my 2010 silverado z71 5.3 with 80,000 miles. I cannot believe this is not a recall!! Has anyone found a true cause and resolution to this issue? This has been going on for way too long now! Come on chevy!!! I'm trying to avoid endless trips to the dealership service department and wasted money on unneeded service as they chase their tails with no resolution. Any help here would be appreciated.
